Summative assessment编辑历史

# 1 Definition and purpose

Summative assessment is a type of educational evaluation that measures student learning, skill acquisition, or academic achievement at the conclusion of a defined instructional period—such as a unit, course, semester, or academic year. Its primary purpose is to assign grades, certify competence, or evaluate the effectiveness of instruction, in contrast to formative assessment, which is ongoing and aims to improve learning during the process. Common examples include final examinations, end-of-term projects, standardized tests, and cumulative portfolios.

## 1.1 Distinction from formative assessment

Formative assessment occurs during instruction and provides feedback to both students and teachers to guide ongoing learning. Summative assessment, by contrast, takes place after learning activities have ended and serves to summarize what has been achieved. While formative assessments are typically low-stakes and diagnostic, summative assessments are often high-stakes and used for final judgments about student performance.

## 1.2 Key characteristics

### 1.2.1 Timing and frequency

Summative assessments are administered at the end of a defined period—such as a unit, semester, or academic year—and occur less frequently than formative assessments. They are typically scheduled at predetermined points in the academic calendar.

### 1.2.2 High-stakes nature

Because summative assessments often determine final grades, academic progression, or certification, they carry significant consequences for students, educators, and institutions. This high-stakes aspect influences both test design and student preparation.

### 1.2.3 Criteria-referenced vs. norm-referenced interpretation

Summative assessments can be interpreted using criterion-referenced standards (comparing performance against a fixed set of criteria) or norm-referenced standards (comparing performance against a group of peers). Criterion-referenced interpretation is common in classroom
